I'm testing with a library IBM 3580 Ultrium 5 HH tape drive in a VMware environment, the idea is to backup all VMs tapes.

To do this I have a (Windows Server 2008 R2 64 Bits) physical server from which you run the UltraBac application 9.4 (demo license), I make the driver settings from the library (Medium Changer Device) successfully, the application I can manage Bookseller.

However, when I erase a tape, or prepare it for use the server collapses, sending a memory dump (blue screen) with error 0x00000019 BAD POOL HEADER, because this error appears?

I worked anteriomente with libraries of different brands but never had this conflict, I know that the blue screen is because there is a bug in the driver, but UltraBac only I have a single driver, so I wonder if have some other driver or possible solution?
